In the context of the requirements dictated by the lessons of the earthquake, the necessity arose to establish a new higher education institution in the Republic, as a result of which the Yerevan Institute of Architecture and Construction was established in 1989 (since 2000 – Yerevan State University of Architecture and Construction, and since 2014 – National University of Architecture and Construction of Armenia).
The university, along with all its infrastructure and subdivisions, was established on the basis of the Yerevan Polytechnic Institute. Similarly, in 1990, on the basis of the Chair of Higher Mathematics of Yerevan Polytechnic Institute, the Chair of Higher Mathematics of Yerevan State University of Architecture and Construction was established, the Head of which was elected Doctor of Physical-Mathematical Sciences, Professor Aramayis Babloyan and from 2008 to 2023 – the Corresponding member of RA NAS, Doctor of Physical and Mathematical Sciences, Professor Suren Mkhitaryan. Professor Stepan Zargaryan was the Head of the Chair of Theoretical Mechanics, and PhD in Technical Sciences, Associate Professor Sergey Melkumyan – the Head of the Chair of Strength of Materials, which was reorganized and renamed the Chair of Theoretical Mechanics and Strength of Materials from 1993 to 1997, the Head of which was appointed Nikolay Sargsyan. The Head of the Chair of Construction Mechanics was Doctor of Technical Sciences, Associate Professor Levon Petrosyan, and from 1995 to 1997 – Doctor of Physical-Mathematical Sciences, Professor Suren Darbinyan. From 1997 to 2023, the Head of Chair was Doctor of Technical Sciences, Professor, Academician of RA NAS, and Honored Worker of Science and Technology of the Republic of Armenia Eduard Khachiyan. In parallel with the educational and methodological activities, scientific-research activities have been held, doctoral and PhD theses have been defended, as well as, if necessary, scientific consultations for the staff of other Chairs of the University have been organized in the Chairs.
Since June 2023, the Chair of Higher Mathematics and Physics, the Chair of Theoretical Mechanics and Strength of Materials, and the Chair of Construction Mechanics have been merged and renamed the Department of Mathematics, Construction Mechanics and Physics, with Doctor of Sciences in Physics and Mathematics. Professor Yurik Stepan Babayan was appointed as the Head of the Department. Currently, the department employs the Doctor of Physical and Mathematical Sciences, Professor Y. Babayan (Head of the Department), Doctor of Physical and Mathematical Sciences, Professor K. Aghayan, Associate Professors H. Kanetsyan, M. Mkrtchyan, V. Yedoyan, M. Grigoryan, S. Sargsyan, L. Soghomonyan, L. Levonyan, S. Gabrielyan, N. Arevshatyan, G. Ter-Petrosyan, S. Valesyan, assistants N. Evoyan, D. Melkonyan, lecturers N. Vasilyan, H. Harutyunyan, and PhD student S. Malumyan, along with administrative employees G. Shahverdyan, M. Abgaryan, and L. Serobyan.
The Department of Mathematics, Construction Mechanics, and Physics is university-wide and serves students, graduate students, and PhD students of all Faculties/except the Faculty of Design/.
In parallel with the educational activities of the Department, scientific research activities are conducted dedicated to the application of integral equations and integral transformations in boundary value problems of Solid Mechanics, special functions of Mathematical Physics, and boundary value problems of analytic functions. Under the leadership of Yuri Babayan, a scientific seminar was held at the Philip-Morris Lori Tufenkian Hotel Complex, and a scientific seminar on “The Effect of Electromagnetic Waves on Aqueous Solutions” will take place in December. The department has developed educational-methodical materials, accessible methods of presenting complex topics, and new educational programs for architects and builders (according to their specialties), which have been discussed during ongoing scientific-methodical seminars of the Departments. As a result, dozenս of educational-methodical manuals have been revised and published by the lecturers.
The Department conducts scientific-research activities in the following fields:
- Applications of Fredholm and singular integral equations in boundary value problems of Solid Mechanics;
- Development of methods for obtaining spectral and related integral relations using potential theory methods for integral operators of certain classes of mixed boundary value problems of Mathematical Physics;
- Applications of methods of integral equations and integral transformations in contact and mixed boundary level problems of Mechanics of Solid Deformable Body, in Fracture Mechanics, and boundary value problems in the Theory of Filtration of Liquids in Porous Media;
- Asymptotic and other mathematical methods of the mechanics of thin-walled bodies;
- Problems of Theory of Applied Elasticity;
- Study of the Interconnected Fields;
- Study of Seismic Resistance;
- Mechanics of Composite Materials;
- Prediction of synthetic seismograms and accelerograms of the ground in case of strong earthquakes, considering the earthquake as an instantaneous rupture of the Earth’s crust;
- Calculation of structures and their load-bearing elements under static and dynamic effects, taking into account the spatial and non-linear work of load-bearing elements;
- Solid Mechanics, Mechanics of Deformable Body, Slabs and Membranes, Hydrodynamics, Vibrations and Stability, Theory of Plasticity, and Theory of Creep.
- Stress-deformed state of load-bearing elements under the combined effects of bending and twisting, material inhomogeneity, and non-elastic deformation conditions.
